I wish there were some sort of guidebook or phrasebook that lists different Christian slang, jargon, vocabulary, that insiders of a particular Christian group use but outsiders will have no idea what they are really saying or have a vague sense of what they are saying.
If not, is asking questions about Christian jargon appropriate here?
What is a mission trip?
Since when did Mormons use "tracting" to refer to door-to-door proselytizing?
How did the phrase "getting to know Jesus" come to be ubiquitous among Evangelicals? To them, what is it really supposed to mean? Does it refer to the act of converting to Christianity, or does it refer to the act of living a Christian lifestyle? Can a person "know Jesus" but still not commit to Jesus's teachings?
What do Evangelical Christians mean by "seeing Jesus"? What is the etymology of this phrase?
For the third question, I've only seen the question when Cru (Campus Crusade for Christ) promotes at my school and on websites. I think other English-speaking Evangelicals do it too.
